I am the security administrator for the mainframe. I work in the systems programming department, where we have DBAs. The DBAs believe that they should have the same security access as the mainframe systems programmers. I don't believe this should happen, but I am having a hard time convincing the assistant vice president that they should not have the same access. Do you have any suggestions? >> CLICK for Mark's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid501501_tax287555,00.html >> CLICK to discuss this topic in the Sound Off forum: http://search390.discussions.techtarget.com/WebX?msgInContext@;109.wc20ahLpuVy.0@.ee83ff9/206!viewtype=&noconfirm=noconfirm =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= WILL MAINFRAME JOBS CONTINUE TO GO OVERSEAS? | by Rick Nashleanas Dear Ask the Expert, In the mainframe job trend question you answered, you said: "On the negative side, outsourcing overseas poses a serious threat to a major rebound. This overseas outsourcing started simply as a cost reduction technique but is now fueled by a lack of qualified natives in the US." Does the last sentence imply that older mainframers like myself, who are not ready to retire, have a good chance in the market or will these jobs continue to go overseas? >> CLICK for Rick's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid500996_tax285449,00.html >> CLICK for Rick's mainframe job market forecast: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid499817_tax285449,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= NEED HELP WITH DB2 PERFORMANCE IMPROVEMENT? | by Tom Moulder Dear Ask the Expert, A consulting customer of mine has asked me to examine a large OS/390 (zSeries) system using DB2 V6 and give some performance improvement recommendations. I have two questions: 1. I would like to suggest the client investigate concurrency control using versioning instead of traditional locking. Does DB2 support this kind of optimistic concurrency control? 2. Years ago, I obtained a substantial improvement in a system by using a shared memory region and having the DBMS return the "results table" to that memory space. The application then had direct access to the table entries and avoided many, many context switches going back to the database using a FETCH. This client's system has the application and DB2 running on the same box and would seem to be a candidate for this same technique. Will it still work? >> CLICK for Tom's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid500966_tax286336,00.html ___________________________________________________________________ SPONSORED BY: IONA GO FROM 3RD-GEN TO OBJECT-ORIENTED WITH NO PAIN, RETRAINING OR DOWNTIME Are you facing pressure to migrate your mainframe systems to new technologies such as Java and EJBs?

Search390.com user "Samaga" posted the following in the Developer forum: "I have written an 'environment-independent' program. By that I mean it can be called in both CICS and batch mode. In this program, I have DISPLAY statements for debugging. Until the other day, this was working fine when called in CICS. Now I'm getting an 'AZI6' abend at the offset where DISPLAY is written. What could be the reason for this? How is DISPLAY interpreted by CICS? >> CLICK to read advice from another 390 user, or to post a response of your own: http://search390.discussions.techtarget.com/WebX?msgInContext@;157.fcHCaihEuU3.4@.ee83ff7/624 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= FEATURED BOOK | Enterprise Java programming with IBM WebSphere Do you want techniques for an efficient e-commerce solution?
